JOHN CLEGG, OF PROVIDENCE, RHODE ISLAND.

PLUMBERS FURNACE.

Application filed November 11, 1885. Serial No. 182,460.

To all whom, it may concern.-

Be it known that I, JOHN OLEGG, of Providence, Providence county, Rhode Island, have invented a new and Improved PlumbersFurnace, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved plumbers furnace for melt ing lead, 850., which furnace is simple in construction and is provided with means for produoing a very powerful draft in a very short time.

The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawing, forming part of this specification, in which a cross-sectional view of my improved plumbers furnace is shown.

The cast-iron or other pot or bowl A is firmly bolted or otherwise secured on the top of the metal frame B, which is secured on the base 0, of wood or metal. The pot A has an aperture, D, in the bottom, and into said aperture the neck F of the blower-casing G projects, the wings or fans H being mounted on the shaft J, within the said casing. A pinion, L, is mounted on the shaft J, and engages with the cog-wheel M, pivoted on the frame B,and united with the pinion N, engaging with the cog-wheel O, pivoted on the frame B, and pro vided with a crank-handle or other device'for turning it, and thus revolving the fan in the blower very rapidly and producing a very powerful air-current, which is delivered direct on the charcoal in the pot A, and on the said charcoal the pot containing the lead or other metal to be melted is placed. As a very high (N0 model.)

degree ofheat is produced in a short time the it is to be used.

All that is necessary to produce a very high degree of heat is to operate the blower by turning the cog-wheels.

The pot A may be provided with acover, to prevent sparks flying out.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- 1. A portable furnace for plumbers use, comprising a base, 0, an open frame, B, mounted thereon, the fire-pot D, having a central opening in its bottom and secured to the top cross-pieces of the frame, a blower on the base below the fire-pot having a neck, 13, registering with opening in the bottom of the fire-pot, the shaft J, having the wings H within the blower, and the operating-gear for said shaft, substantiaily as set forth.

The combination, with a portable melting pot provided in its bottom with an aperture, of the frame B, on which the said pot is secured,

a blower on said frame and below the pot, and

provided with a neck extending into the aperture in the bottom of the pot, cog-wheels pivoted on the said frame B for driving the blower, and of the bail R on the melting-pot, substantially as herein shown and described.

JOHN OLEGG.
